1449 Virtanen, provisional designation 1938 DO, is a stony Florian

Artturi Virtanen.[2]

Description

Virtanen is a member of the

Heidelberg, extending the body's observation arc by 10 years prior to its official discovery at Turku.[15]

Physical characteristics

In the

Tholen taxonomy, Virtanen is classified as a common S-type asteroid.[1]

Lightcurves

Virtanen's first rotational

U=2-/3-/3-).[9][10]

Additional periods were obtained from photometric observation in the R and S-band at the

U=n.a.).[11][12]

Diameter and albedo

According to the survey carried out by NASA's

albedo between 0.285 and 0.36.[4][5][6][7]

The Collaborative Asteroid Lightcurve Link assumes an albedo of 0.24 – derived from 8 Flora, the largest member and namesake of its family – and calculates a diameter of 10.31 kilometers with an absolute magnitude of 12.1.[3]
